**GSE**: STRUCTURAL ENGINEERING SOFTWARE

ANALYSIS AND DESIGN SOLUTION FOR BUILDINGS & STRUCTURES

G S E A L U M I N U M D E S I G N

Part of the GSE Software, GSE ALUMINUM is the industry standard for the design and verification of aluminum of any type. The unmatched graphical user interface of the GSE software allows to create, analyze and design large and complex models quickly and easily.

The program designs or verifies the whole or a part of a structure according to the Canadian CAN/CSA S157-05 design code using standard sections or parametric section shapes (over 30 shapes available).

The GSE ALUMINUM allows to verify aluminum members with standard sections and non-standard sections. The GSE ALUMINUM is made to let the user retain full control over the design process.

All parameters required to calculate the resistance of the elements such as unbraced lengths, buckling lengths, buckling factors, end welding, in span welding, slenderness limit, and others. They can be customized either graphically or from spreadsheets.

## ALUMINUM STRUCTURES VERIFICATION

ALUMINUM STRUCTURES VERIFICATION

The program calculates the bending, compression, tension, shear and combined resistance of aluminum based on the results of a linear, P-Delta, non-linear, seismic, dynamic or moving load analysis. Singly symmetric, asymmetric and built-up section shapes are covered for all design codes.

## COMPRESSION

COMPRESSION

The compressive resistance (Cr) of a member is calculated according to clauses 9.4.1, 9.4.2 and 9.4.3. The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.

The torsional buckling stress is calculated using the method presented in clause 13.3.2 of the CAN/CSA S16 code from where the equations of clauses 9.4.3.2 and 9.4.3.3 of the CAN/CSA-S157 code are taken (see commentary C9.4.3.3).

The compressive resistance of a built-up section is calculated according to clause 9.8.2.

## TENSION

TENSION

The tensile resistance (Tr) of a member is calculated according to clause 9.2.1.

## BENDING

BENDING

The bending resistance (Mr) of a member is calculated according to clauses 9.5.2 (resistance of the cross section) and 9.5.3 (lateral torsional buckling). The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.

The lateral torsional buckling resistance is calculated using the general lateral torsional buckling equation. The equation presented in clause 9.5.3.2 is a simplification of this general equation.

## COMPRESSION -BENDING

COMPRESSION -BENDING

The compression-bending resistance of a member is calculated according to clauses 9.7.3.2 (flexural buckling without lateral torsional buckling) and 9.7.3.3 (flexural buckling and lateral torsional buckling). The equation presented in clause 9.7.3.3 used in the calculations is modified to account for biaxial stresses.

An additional verification is made with respect to the resistance of the cross section. This verification is an

adaptation of equation 13.8.2 a) of the CAN/CSA S16 code.

## TENSION - BENDING

TENSION - BENDING

The tension-bending resistance of a member is calculated according to clauses 9.7.1.1 (resistance of the cross section) and 9.7.1.3 (stability).

## SHEAR

SHEAR

The shear resistance (Vr) of a member is calculated according to clauses 9.6.1.1, 9.6.1.2 a) and 9.6.2.2.

## WELDS

WELDS

The welds have an important influence on the resistance of aluminum elements. The program distinguishes two types of welds which are end welds and in-span welds. Each of these types of welds may be full (affecting the entire cross section) or partial (affecting a portion of the cross section).

In the case of full welds, R Ag, R Ix and R Iy are not used.

In the case of partial welds, ratios must be specified.
